Forest stand mapping with digital stereoplotter Digital Images, Analytical Plotter (DiAP) is presented. Two forest stand maps were created with the stereoplotter for Pokljuka (173 ha) and Leskova dolina (187 ha) test areas. Forest was delineated into stands with the use of photo interpretation key, which was based on stand structure, development stage, type and form of stand mixtures, canopy closure and canopy cover. Minimal area of 0,5 ha was considered during the mapping of forest stands, but in the case of young growth smaller minimal area (0,1 ha) has been suggested. Newly made forest stand maps were compared to already existed maps for our test areas. Furthermore, the quality of spatial data set in the existent maps was estimated in accordance to ISO 19113 standard. The estimation revealed adequate quality for forest stand map for Pokljuka, while some deficiencies were noticed in the map for Leskova dolina. Numerous errors and reduced usage of forest stand maps are present when mapping is made without the stereoscopical observation of spatial model. Exact creation of the first forest stand map ensures easier and reasonable maintenance. We suggest the correction of those lines in older forest stand maps, where stand borders havebeen changed in the last ten years, in other cases just the code number offorest stand should be corrected when necessary. We expect that the applicability of stand maps will increase during the next years. The usefulness of stand maps has already been proved in the forest management and there are some possibilities of using them in terms of biodiversity monitoring.
